Title: Ac semiconductor switch
Inventor: SAWAJIMA HAJIME
IPC: H01L29/74
Filed: 1980-02-19
Abstract: PURPOSE:To make it possible to open and close a composite element of a triac and a unilateral thyristor by a single pulse by arranging the P base, P emitter and N emitter into a specified structure. CONSTITUTION:The composite element is constituted by a triac of five-layer structure consisting of N1, P1, N2, P<2> and N3 and a SCR of four-layer structure consisting of N4, P3, N2 and P2. Moreover, the triac is functionally separated into a thyristor 1 consisting of N1, P1, N2 and P2' and a thyristor 2 consisting of N3, P2, N2 and P1'. When a gate trigger is inputted to the gate terminal in the triac portion of the composite element of such structure, the thyristor 1 condusts. Then, when the main power source reverse polarity, because the critical rate of rise of blocking voltage of the thyristor 2 is lower than the rate of rise of supply voltage, the thyristor 2 conducts while the thyristor 1 is in blocking state because of a reverse bias. On the other hand, when a gate trigger is applied to the gate terminal Gs in the SCR portion to allow the SCR to conduct, because the triac portion has a higher conducting voltage than the SCR pirtion, the triac is in blocking state during the succeeding commutation period.

Abstract: PURPOSE:To charge and discharge capacitor in accordance with a peak value of an input pulse train by providing a peak holding section 1, a pulse train detecting section 2 detecting that a pulse is inputted, and a control section 3 for discharging a capacitor. CONSTITUTION:Contrivance is made so that a pulse train (II) having a peak value smaller than that of a pulse train (I) be inputted. When the pulse train (II) is inputted, a peak hold value Vpkc of a peak holding section 2 is turned to be lower than a peak value Vin2 of the pulse train (II), and therefore a comparator 21 gives an output signal of '1' to an analog switch 24 so as to charge a capacitor 22. On the occasion, a comparator 11 outputs '0'. As the result, a logic circuit 3 outputs '1' and a capacitor 12 is discharged with a constant current I3. Accordingly, a peak hold value of a peak holding section 1 decreases rapidly.
